SF AIDA OR EVIDENCE PLATINUM W MOMENTUM PRE & AMP

Yeah, 'if done right' is the key. The room should be precisely tuned too, in this case especially so, I assume.
Hell, I just put one Walker resonance control disc on my Nakamichi deck, somewhere in the middle, and there was a small but noticeable improvement in clarity, and the deck already sits on Boston Audio tuneblocks. Imagine what can be done to a room and speakers together.

Duke, I am sure that you are correct. However, you use the term 'room treatment' while I say 'tuning' speaker/room pair. Are we talking about the same thing? I don't know. I share Michael Green's idea about tuning the entire system.
Grand piano will not sound good in smaller room, but guitar will. Tuned guitar. Grand piano will sound more or less acceptable, if you are lucky.
You move one chair out of the room leaving everything else as it was and the acoustics changes, sometimes significantly. No speaker design can compensate for what must be done working with the entire whole. At least I think so.

Duke, you are a pro, I am a listener. I can try to put it as a layman. I thought that the speakers/room system as presented by you is a bit mechanical. I believe it to be more as a kind of diad, a symbyosis of a sort, singing with one voice that contains the interactions of all reproduced instruments. As an instrument, in a manner of speaking.
And every instrument must be tuned. What does it mean in practical terms? I don't know, we better ask Michael Green. He tunes studios and performance halls. He 'listens' to wood before making platforms on which particular singers stand when singing, puts his panels wherever he feels they should be, moves chairs etc.

Duke, I too think that in fact we are basically in agreement.
